HS: Statistics [M] (Sequential) Estimates and Sample Sizes5. Find the critical values-example-1

We are asked to find the left and right critical values.

The confidence level is 95%

Significance level = 1 - 0.95 = 0.05

Sample size: n = 9

Degree of freedom = n - 1 = 9 - 1 = 8

So, the significance level is 0.05 and the degree of freedom is 8.

Using any chi-square critical value table or calculator,

Left critical value: χ²L = 2.733

Right critical value: χ²R = 15.507

Therefore, the chi-square left and right critical values are

2.733, 15.507
